The present invention relates to pull bar structures for removing a front panel of a computer case, and more particularly to a pull bar structure that simplifies the processes of connecting/disconnecting a front panel with a computer case.
Because of the rapid development of the information industry, personal computers have become a common appliance in every family. Many of the users are now equipped with basic abilities of maintaining and upgrading the hardware of a personal computer.
The above-mentioned personal computers mainly include a case that not only contains the computing components but also plays the role of structural support. A front panel, a left-side panel and a right-side panel for ornamenting the case and reinforcing the structure cover the case. When moving the computer device, the major force is applied to the front panel. To prevent the front panel from falling off the case in a process of moving, the right-side panel and the left-side panel are designed to be locked with the front panel in the prior art.
However, to maintain or upgrade the components within the computer case, both of the left-side panel and the right-side panel should be removed before taking off the front panel, which complicates the removing process and wastes a lot of time.
Accordingly, the primary objective of the present invention is to provide a pull bar structure in a computer case that can simplify the process of removing the front panel and therefore save a significant amount of time.
To achieve the objective, the present invention as a computer case having a pull bar structure for removing a front panel comprises a case, a front panel and a pull bar, wherein the case includes a front wall and a bottom wall; the bottom wall connects with the bottom edge of the front wall; an aperture is formed on the front wall; a first guiding means is transversely formed on the bottom wall.
The front panel is mounted on the front wall of the case. The front panel is further provided with a fixing member uprightly extended from the backside thereof. The fixing member is located corresponding to the aperture of the front wall, with a fixing hole transversely formed at the free end thereof.
The pull bar includes a second guiding means and a pressing plate. A bulged fixing dot is formed on the pressing plate. The second guiding means is located corresponding to the first guiding means. The second guiding means is slid with the first guiding means to achieve the pull bar transversely slides on the bottom wall so that the pull bar can slide in a transverse direction on the bottom wall, and to achieve a slidable connection of the bulged fixing dot with the fixing hole.
Therefore, in either of mounting and removing processes of the front panel, removing both of the right-side panel and the left-side panel is not necessary. To remove the front panel of the present invention, only one of the side panels is removed first, and then the pull bar is pulled outwardly so that the bulged dot thereof is decoupled with the fixing hole of the front panel. Compared with the conventional computer cases, the present invention indeed simplifies the mounting/removing process of a front panel and thus saves people a significant amount of time.
Further, a fixing tab is formed on the front wall of the case, which is uprightly extended from the rim of the aperture toward the interior of the case. A bulged locking dot is formed on the fixing tab, and the fixing member of the front panel is provided with a locking hole located corresponding to and engaging with the bulged locking dot when the front panel is mounted on the front wall.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings.
The above-mentioned front panel 2 is provided with a fixing member 21, which is uprightly extended from the inner side of the front panel 2. A locking hole 212 is formed at the free end of the fixing member 21, and a fixing hole 211 is transversely formed at the free end of the fixing member 21. As shown in
To remove the front panel 2, the left-side panel 91 is firstly taken off, and an operation portion 34 of the pull bar 3 is pulled so as to slide the pull bar 3 along the bottom wall 12 in the direction as indicated by an arrow in FIG. 2A. Meanwhile, the bulged fixing dot 321 of the pressing plate 32 is departed from the fixing hole 211 on the fixing member 21 of the front panel 2. Referring to FIG. 3A and
The present invention is thus described, and it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
